I wrote a simple theme extension: { "name": "Tomorrow Night", "manifest_version": 2, "version": "1.0", "theme": { "colors": { "accentcolor": "#282a2e", "textcolor": "#b4b7b4", "tab_selected": "#373b41", "tab_text": "#c5c8c6", "toolbar": "#373b41", "tab_line": "#373b41" } }, "applications": { "gecko": { "id": "tomorrow-night@carlos.me" } } } I'm able temporarily install it from about:debugging. So I built a zip and tried to install it as an addon from a file. Without the applications key firefox says the file is corrupted. With the applications key it says it can verify its signature. I can't submit it for verification in AMO because it rejects it saying it's a theme extension which are not yet supported. So what can I do with this extension? Can't install it locally, can't publish it, can't verify it without publishing. How am I supposed to install this simple theme for personal usage?
